Description

Technical Field

[0001] This utility model relates to bracket fixation devices, and more particularly to a bracket fixation device for oral orthodontic treatment, belonging to the field of oral orthodontic technology. Background Technology

[0002] Orthodontic brackets are a core component of the orthodontic system and an important part of fixed orthodontic appliances. They are fixed to the tooth surface with adhesive to hold the orthodontic archwire. The archwire's elastic deformation generates corrective force, guiding the teeth to their intended positions, thereby achieving proper tooth alignment and improved occlusion.

[0003] Publication number CN211433406U discloses a bracket fixator for orthodontic treatment, belonging to the field of orthodontic technology. It includes a fixator body with multiple sets of fixing clips evenly arranged on its outer side. A memory wire is inserted into the inner side of each fixing clip. An upper clip is located at the top of each fixing clip, and a lower clip is located at the bottom of the upper clip. Multiple sets of locking blocks are evenly arranged at one end of the bottom of the upper clip, and multiple sets of protrusions are evenly arranged at one end of the top of the lower clip. This bracket fixator uses a rubber pad composed of rubber blocks and rubber sheets, forming an "I" shape. This allows the rubber pad to be secured in the holes, eliminating the need for adhesive liquid to fix the rubber pad to the fixing clips. This avoids the adhesive liquid being corroded by saliva, prevents the rubber pad from shifting and separating from the fixator, thus increasing its service life and improving work efficiency to a certain extent.

[0004] When using this type of orthodontic bracket fixation device, it needs to be kept in a fixed position to ensure the orthodontic effect, just like traditional products. However, as the orthodontic rehabilitation process progresses, the alignment of the teeth changes continuously, and the position of the originally installed fixation device may no longer be suitable for the new orthodontic needs. Since the device lacks a position fine-tuning function, users often find it difficult to make flexible adjustments according to the dynamic changes of the teeth. This not only affects the orthodontic effect, but may also lead to a significant extension of the rehabilitation period, thus requiring improvement.

[0005] Therefore, a bracket fixation device for oral orthodontic treatment is proposed. Utility Model Content

[0006] In view of this, the present invention provides a bracket fixation device for oral orthodontics to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-5As shown, this utility model embodiment provides a bracket fixation device for oral orthodontics, including an adhesive plate 1, a groove plate A2 mounted on the adhesive plate 1, a slide plate 3 slidably mounted in the groove plate A2, a lead screw 4 rotatably mounted in the groove plate A2, a worm gear 5 mounted on the lead screw 4, a worm 6 meshing with the side of the worm gear 5, the worm 6 rotatably mounted in the groove plate A2, a groove plate B8 mounted on the slide plate 3, a moving block 10 slidably mounted in the groove plate B8, a through groove 9 provided below the groove plate B8, a stud 11 mounted below the moving block 10, a locking nut 12 threadedly connected to the stud 11, an mounting plate 13 mounted on the moving block 10, and a bracket block body 14 mounted on the mounting plate 13.

[0028] In one embodiment, the groove plate A2 is provided with a groove adapted to the slide plate 3. The slide plate 3 is slidably disposed in the groove and can slide up and down along the groove. By driving the slide plate 3 to slide in the groove, the support block body 14 can be adjusted in the Y-axis direction.

[0029] In one embodiment, the worm gear 5 and the lead screw 4 are aligned on the same axis. The self-locking function between the worm 6 and the worm gear 5 ensures that the bracket block body 14 will not displace in the Y-axis direction.

[0030] In one embodiment, the slide plate 3 has a threaded hole, and the slide plate 3 is connected to the lead screw 4 by a thread. During the rotation of the lead screw 4, the threaded engagement between the lead screw 4 and the slide plate 3 will drive the slide plate 3 to perform rapid adjustment along the Y-axis direction along the slot plate A2.

[0031] In one embodiment, an auxiliary handle is mounted on the locking nut 12, and a stud 11 is disposed within the through slot 9. A pry bar is inserted into the auxiliary handle of the locking nut 12, and the locking nut 12 is rotated under the action of the lever principle.

[0032] In one embodiment, a hinged plate 15 is hinged to the bracket body 14, a soft pad 16 is installed on the hinged plate 15, a connecting block 17 is installed below the hinged plate 15, a threaded sleeve 18 is provided inside the bracket body 14, and a threaded pin 19 is provided inside the bracket body 14. This structure can quickly achieve a fixed connection between the bracket body 14 and the archwire. Compared with the traditional elastic band fixing method, this structure can not only be reused, avoiding material waste caused by elastic band consumption, but also solves the problems of high technical skill requirements and low efficiency in traditional elastic band binding operations.

[0033] In one embodiment, the threaded pin 19 and the worm gear 6 are respectively provided with an internal hexagonal groove 7 at one end, and the soft pad 16 is made of natural rubber. The soft pad 16 made of natural rubber can effectively reduce wear on the contact surface with the bowwire, thereby improving the service life of the bowwire.

[0034] In operation, this invention works as follows: First, the bonding plate 1 is fixed to the tooth surface with glue. Then, the archwire is inserted into the groove in the bracket body 14. Next, the opening and closing plate 15 is pulled down, causing the connecting block 17 to reset within the bracket body 14. Then, the threaded pin 19 is inserted into the bracket body 14, passing through the connecting block 17. Next, an Allen wrench is inserted into the Allen groove 7 at one end of the threaded pin 19 and rotated to screw the threaded pin 19 into the threaded sleeve 18, thus completing the fixed connection between the bracket body 14 and the archwire. Precise adjustments to the X and Y axes of the bracket body 14 can be made later according to rehabilitation needs. When X-axis adjustment is required, a pry bar can be inserted into the auxiliary handle of the locking nut 12, and the lever principle will rotate the locking nut 12, causing it to rotate downwards along the stud 11 under the action of the thread, gradually decreasing its position. The top-fixing force on the upper slot plate B8 releases the limiting and fixing effect of the moving block 10 inside the slot plate B8. Then, the moving block 10 and the support block body 14 can slide along the slot plate B8 in the X-axis direction. During this process, the stud 11 will slide synchronously along the through groove 9. After the position adjustment is completed, the auxiliary handle and locking nut 12 are rotated in the opposite direction, and the screw moves upward under the action of the thread. The top-fixing force is applied to the upper slot plate B8 again. When moving in the Y-axis direction, first use an Allen wrench to insert into the Allen groove 7 on one side of the worm 6 and rotate it, thereby driving the worm 6 to rotate. Under the meshing action between the worm 6 and the worm wheel 5, the worm 6 and the lead screw 4 will rotate. Under the threaded engagement between the lead screw 4 and the slide plate 3, the slide plate 3 will be driven to perform rapid adjustment work in the Y-axis direction along the slot plate A2. Under the self-locking function between the worm 6 and the worm wheel 5, it can be ensured that the support block body 14 will not be displaced in the Y-axis direction.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
